Abstract
An endotracheal tube for allowing nasally intubated patients to speak comprising an elongated tube adapted for nasal intubation. The tube has an opening adjacent the patient's throat when intubated, and reed means in the opening. Interconnected first and second valves are at the proximal tube end and the opening, respectively, and are manually operable to open the tube proximal end and close the opening, and vice versa. The patient can breathe through the tube when the tube proximal end is open and the opening is closed. When the tube proximal end is closed and the opening is open, expiring air from the patient's lungs passes the reed means causing it to vibrate and produce an audible tone which can be altered by the patient's mouth and tongue to produce audible speech.
